Subway on Houston Street closes

We are down to three Subways, now. The one on East Houston Street has closed. Not sure what happened, but it might have something to do with too many Subways. From the notice posted on the front door:

We will be closing this location permanently. Sorry for any inconvenience this may cause you. Please visit our locations at 111 Soledad, 109 Alamo Plaza, 100 Santa Rosa. We appreciate your business and Thank You for being our customer. Sincerely, Management
